In 2002, to experience augmented reality was to lash 26 pounds of equipment to your body and hobble waywardly within the confines of predefined area. In 2010, you can augment the entire world with a free app for your smartphone.

This shot of the Columbia University’s Mobile Augmented Reality System(MARS) comes from a PopSci story written 10 Februaries ago. (The magazine’s searchable archives just went online.) This right around the time that augmented reality had made the jump from esoteric sci-fi concept to actual thing, albeit in the form of awkward research projects and simplistic military applications:

If you strap on this rig, as [the writer] had, you begin to understand the profound possibilities of an AR system, which can superimpose computer-generated text, graphics, 3D animation, sound, or any other or any other digitized data on the real world.

The latest talk of the town in the Apple blogosphere is 3D head-tracking. Apple recently filed a patent for technology that allows users to change perspective of an object by moving their head or body. So instead of dragging your mouse to rotate a graph or chart, you simply look behind it; a more intuitive approach (at least in the eyes of Apple engineers). Here’s a quick video of how this could be used to view 3D construction plans:

With all the attention augmented reality is getting, we’re not surprised to see big players like Apple experimenting with this genre of technology. Novelty aside, there seems to be endless applications. We think the technology would be great for the construction industry. Combined with construction software, contractors could use it to visualize complex construction projects, like the example above which uses 3D building models from Synchro software.

Augmented reality will soon be available on smartphones to transform site visits. Written by Simon Johns

Imagine walking down the street, looking for somewhere to eat. You use your phone to photograph a restaurant, and the overlay on the screen shows you menu items pulled from the restaurant’s online menu, reviews from newspapers and so forth.

Science fiction? No, this is available right now from a startup called Layar (www.layar.com), with content from Yellow Pages, Google, Flickr and Wikipedia.

Modern smartphones, such as iPhones and Google Android devices, can determine their own location through GPS and an internal compass, they can download data through mobile broadband connections and they have reasonably powerful graphics-processing capabilities. These provide the necessary ingredients for mobile augmented reality.

Mixed reality and visualization

Competence

Mixed Reality denotes generally different visualisation means between Reality and Virtuality, enabled by 3D computer graphics. On one hand, Virtual Reality (VR) means completely 3D modelled representation of real world, while Augmented Reality (AR) stands for superimposing virtual objects in the user’s view of the real world.

The work by VTT’s Virtual Reality research dates back to the year 1995 when a virtual training simulator was developed for printing industries. After that various VR solutions have been developed for building and construction applications, space applications, and terrain visualisation. VTT’s special assets in VR include e.g. scalable Open Scene Graph (OSG) based viewer implementation, up to immersive CAVE type environments. We also develop application software and browser based solutions for the management and visualisation of various types of contents (text, graphics, images, video, 3D models, etc.). We are specialised in interactive management and visualisation of complex datasets.
